Keys

The "keys" is an item that can be found in the game, at least in escape mode, the phone suggests that it can be used to fix the power outage at the "circuit breaker" but i run across the whole map but couldnt find them. Please help me out and explain if you found out

Locations
The keys can be found at random locations in the hosts, often upstairs if you did not found them downstairs..

Usage


I dont have the slightest idea how to use it to unlock everything else then imaginary locks out of thin air...
